Weld Profile
The external geometry of a weld including reinforcement height, width, and contour. Proper weld profile is essential for stress distribution and fatigue resistance. Excess reinforcement increases stiffness but is wasteful; insufficient reinforcement may be unacceptable. Visual inspection and measurement of weld profile is the first NDT step. Profile defects like undercut and irregular surface must be detected and evaluated per acceptance standards.

Detection and Assessment
Weld Profile must be detected early and accurately characterized to determine safety implications. Multiple NDT methods may be required for comprehensive evaluation.
Acceptance Criteria
Industry standards such as ASME Section V, AWS D1.1, and API standards provide specific acceptance limits. Whether a detected weld profile is acceptable depends on material, component function, and applicable code.
Best Practices
- Always follow applicable NDT standards and procedures
- Use properly calibrated and maintained equipment
- Ensure personnel are properly trained and certified
- Document inspection procedures and results completely
- Keep current with industry standards and best practices
